TL;DR

Credit Risk helps setting credit limits and pricing by clarifying probability of default and loss given default and the trade‑offs between risk and liquidity constraints. It keeps scope and assumptions aligned.

Definition

Credit risk is the chance that a borrower or customer fails to pay as promised, causing losses. It specifies the unit of analysis and the assumptions behind probability of default and loss given default, including cash-flow timing and discount-rate assumptions. The concept separates what is in scope (cash flows, funding costs, and returns adjusted for risk) from what is out of scope (sunk costs or one-off accounting noise), so comparisons stay consistent. Applied well, it turns a vague debate into a measurable choice and makes the drivers of results explicit.

Decision impact

• Use Credit Risk to decide setting credit limits and pricing, because it exposes probability of default and loss given default and the trade‑off with risk and liquidity constraints.
• It changes budgeting and prioritization by making cash-flow timing and discount-rate assumptions explicit and reviewable.
• It informs adjustments when interest rates or credit spreads change, so the decision stays grounded in current conditions.

Key takeaways

• Define the unit and time horizon before comparing probability of default and loss given default across options.
• Track the primary driver (cost of capital) separately from secondary noise.
• Run sensitivity checks on discount rate and cash-flow timing to avoid false precision.
• Document data sources and calculation steps so results are auditable.
• Revisit the metric when the business model or market context changes.

Misconceptions

• Credit Risk is not the same as demand risk; it focuses on counterparty repayment risk.
• Higher probability of default and loss given default increase expected losses and require stronger risk controls.
• Short‑term changes can mislead when returns arrive after a long ramp-up.

Worked example

A team compares extend 60‑day terms versus require prepayment. Using probability of default and loss given default, they model PD 2% with LGD 45% vs PD 8% and test cash-flow timing and discount-rate assumptions. The analysis shows that terms are tightened for higher‑risk accounts, so they align credit terms with expected loss. After implementation, they monitor cost of capital and update the model when macroeconomic stress rises.
